Despite their reliability, OPzV batteries can experience issues if not maintained properly. Here are common problems and solutions:
1. Sulfation
- Cause: Undercharging or long-term storage without charge.
- Solution: Apply an equalization charge (controlled overcharge) to break sulfate crystals.
2. Dry-Out (Electrolyte Loss)
- Cause: Overcharging or high ambient temperatures.
- Solution: Monitor charging voltage and ensure proper ventilation.
3. Capacity Loss
- Cause: Repeated deep discharges or aging.
- Solution: Perform a capacity test and replace if capacity drops below 80%.
4. Terminal Corrosion
- Cause: Acid leakage or moisture exposure.
- Solution: Clean terminals with a baking soda solution and apply anti-corrosion gel.
Regular inspections prevent most of these issues.
